0.1 Isogonal Conjugate

The isogonal conjugate of a point \(P\) with respect to a triangle is an interesting well-defined point that can be expanded to different techniques and patterns. Although the name suggests the definition of the point, here is the definition.

Definition 0.1.1

The isogonal conjugate of a point \(P\) with respect to a triangle \(ABC\) is the intersection of the reflections of \(AP, BP, CP\) with respect to the angle bisectors at \(A\), \(B\), and \(C\).
